A robust speed controller for induction motor drives
IEEE Transactions on Industrial Electronics, 1994A speed controller considering the effects of parameter variations and external disturbance for indirect field-oriented induction motor drives is proposed in this paper. First a microprocessor-based indirect field-oriented induction motor drive is implemented and its dynamic model at nominal case is estimated.

Control of Induction Motor Drives
1985When comparing the dynamic model of a separately excited DC machine, Eqs. (5.1–5.4), Fig. 5.4, with that of an AC induction machine, Eqs. (10.38–10.41), Fig. 10.16, it is obvious that the latter represents a much more complex control plant. This is caused by the fact that the main flux and the armature current distribution of a DC machine are fixed in ...

An adaptive speed sensorless observer for induction motor drives
IECON '98. Proceedings of the 24th Annual Conference of the IEEE Industrial Electronics Society (Cat. No.98CH36200), 2002An adaptive speed sensorless fourth order observer for online estimating rotor flux and speed in induction motor drives is presented in the paper. The synthesis procedure of the adaptive observer is based on the hyper-stability theory. Assuming the speed as unknown parameter of the rotor flux observer, the online identification process of its value has

A model reference identification technique for induction motor drives
Proceedings of the 1996 IEEE IECON. 22nd International Conference on Industrial Electronics, Control, and Instrumentation, 2002Real-time identifiers of the rotor parameters of an induction motor drive are presented in the paper. The synthesis procedure of the identifiers is based on the MRAC system theory. An appropriate choice of the reference model allows a Lyapunov function to be built up by means of which the updating law of one of the above mentioned parameters can be ...

Adaptive Learning Control for Induction Motor Servo Drives
2007 IEEE International Symposium on Industrial Electronics, 2007The output feedback tracking control problem for induction motor servo drives with mechanical uncertainties is addressed. Under the assumption that the reference profile for the rotor angle is periodic with known period, an adaptive learning control is designed, which "learns" the non-structured unknown periodic disturbance signal due to mechanical ...

Concatenated induction motors for rolling mill drive
Proceedings of the American Institute of Electrical Engineers, 1914The paper describes a six-speed concatenated induction motor set for driving the finishing rolls of a 12-stand continuous mill. Analysis of the conditions in this mill showed that the use of a low-pressure turbine would lead to the waste of a large amount of exhaust steam and that the alternating-current turbine plant which was in operation had ample ...

Output filters for PWM drives with induction motors
Conference Record of 1997 Annual Pulp and Paper Industry Technical Conference, 1998When an induction motor is energized from a pulse width modulated (PWM) inverter, through long connecting cables, its insulation system can be severely stressed. The high dv/dt voltage pulses at the output of the inverter cause traveling waves in the connecting cable between the inverter and the motor. When the traveling wave reaches the motor, a large

Induction motor simulation for the computer aided design of induction motor drives
2010An inverter induction motor drive simulation program for use in power electronic design has been written. The various components which must be represented in an inverter induction motor simulation program are described. The induction motor equations are considered and a simplifying transformation is used in the simulation program.
